The Phosphorus Cycle01:21

The Phosphorus Cycle

44.1K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Chirality at Nitrogen, Phosphorus, and Sulfur02:30

Chirality at Nitrogen, Phosphorus, and Sulfur

7.1K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.6K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

The Bohr Model02:18

The Bohr Model

81.1K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Stereotype Content Model02:16

Stereotype Content Model

15.5K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

  • There is a pressing need for phosphorus recovery and circular economy strategies in resource management.

Purpose of the Study:

  • To explore the potential of microalgae for phosphorus recovery from wastewater.
  • To investigate the molecular mechanisms of phosphorus uptake and storage in microalgae.
  • To review existing phosphate models for understanding phosphorus dynamics.

Main Methods:

  • Review of scientific literature on phosphorus uptake by microalgae.
  • Analysis of phosphate models relating growth rate to intracellular and extracellular phosphorus.
  • Examination of P-enriched algal biomass as a biofertilizer.

Main Results:

  • Microalgae demonstrate significant potential for sequestering phosphorus from wastewater.
  • P-enriched algal biomass can be effectively utilized as a biofertilizer, closing the nutrient loop.
  • Phosphate models provide insights into the kinetics and regulation of phosphorus assimilation.

Conclusions:

  • Microalgae-based phosphorus recovery is a viable strategy for sustainable agriculture and environmental protection.
